Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If Palmae plants are used as raw material for fiber board manufacturing, then alternative material availability is improved, but storage property deteriorates due to poor storage stability and quick decay

Engineering Contradiction:
Improvealternative material availabilityVSAvoidstorage property
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The Palmae plants are ground into fine particles and dried before being used as raw material. This preliminary processing stabilizes the material by removing moisture that causes decay, while maintaining the alternative material benefit. The ground and dried state allows for better storage stability without sacrificing the use of Palmae plants as an alternative raw material source.

Inventive Principle:
Principle #10Preliminary action

2Adaptability or versatility

If Palmae plants are used as raw material, then material availability is improved, but bulk density deteriorates due to low bulk density after drying

Engineering Contradiction:
Improvematerial availabilityVSAvoidbulk density
Core Design Contradiction:
Adaptability or versatilityVSVolume of stationary object

Solution Approach 1:

The Palmae plants are ground into fine particles, which fundamentally changes the physical parameters of the material. This size reduction increases the bulk density by eliminating air gaps between large plant structures, while still maintaining the use of Palmae plants as the raw material source. The parameter change from whole plants to ground particles resolves the bulk density issue.

Inventive Principle:
Principle #35Parameter changes

3Quantity of substance

If ground products of Palmae plants are used directly, then material utilization is improved, but manufacturing precision deteriorates due to fine particles causing defects

Engineering Contradiction:
Improvematerial utilizationVSAvoiddefect rate
Core Design Contradiction:
Quantity of substanceVSManufacturing precision

Solution Approach 1:

The ground products undergo preliminary drying and size classification before being used in fiber board manufacturing. This preliminary action removes excess moisture that would cause defects during processing, and classifies particles by size to ensure uniform distribution in the final product. The fine particles are thus prepared in advance to prevent manufacturing defects while maintaining high material utilization.

Inventive Principle:
Principle #10Preliminary action

4Reliability

If dried ground products are used, then storage property is improved, but transportation efficiency deteriorates due to low bulk density

Engineering Contradiction:
Improvestorage propertyVSAvoidtransportation efficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The ground products are compressed into compressed material with increased density. This parameter change in density improves transportation efficiency by reducing the volume occupied per unit mass, while the ground and dried state maintains storage stability. The compression process resolves the transportation inefficiency without compromising the storage properties achieved through prior drying.

Inventive Principle:
Principle #35Parameter changes
